About this study

Official title: Multi-Center, Non-controlled, Prospective Radiostereometric Analysis of the Pinnacle Acetabular Shell

The primary objective is to establish the mean superior cup migration of the Pinnacle Acetabular Shell using model-based RSA over the first two years post-implantation. The primary endpoint is the mean vertical subsidence (Y translation, also known as superior cup migration) at 2 years as measured with RSA. This will be summarized for each surgical approach separately, as well as combined.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Mean Superior Cup Migration (Subsidence) at 6 Week and 2 Years

    RSA measured mean superior cup migration (subsidence: Y translation in mm) at 6 week and 2 years for each surgical approach separately, as well as combined

    Measured: At 6 week and 2 years

  2. Patient Reported Outcome Measures (PROMs)- HOOS Jr.

    Hip Disability and Osteoarthritis Outcome Score, Joint Replacement (HOOS, JR) is a patient reported joint-specific score designed to evaluate outcomes after total hip arthroplasty. It assesses patient pain (2 items), and functions of daily living (4 items). Response to each item is scored from 0 (none) to 4 (extreme). Raw scores are added up and then converted to an interval score (0-100) using an interval table. The final interval score represents a patients total joint disability where 0 corresponds to total joint disability (worse outcome) and 100 is perfect joint health (best outcome).

    Measured: Pre Operation (-Day90 to Day 0), At 6 weeks, 3 months, 6 months, 1 year and 2 years

  3. Patient Reported Outcome Measures (PROMs)- FJS-12

    The Forgotten Joint Score (FJS-12) is a patient-reported outcome measure intended to determine a patient's ability to "forget" about their affected joint after surgery or treatment. The Forgotten Joint Score consists of 12 questions with response ranging from 0 (never) to 4 (mostly). All responses are summed and then divided by the number of completed items. This mean value is subsequently multiplied by 25 to obtain a total score range of 0 to 100. Finally, the score is subtracted from 100, to change the direction of the final score in a way that high scores indicate a high degree of "forgetting" the artificial joint, that is, a low degree of awareness.

    Measured: At 6 weeks, 3 months, 6 months, 1 year and 2 years

Secondary outcomes (6)
  1. RSA Measured Subsidence of the Pinnacle Acetabular Shell at 3 Months, 6 Months and 1 Year

    Measured: At 3 months, 6 months and 1 year

  2. Other RSA Measurements (X-Translations)

    Other RSA measurements (X translations in mm) at all time points

    Measured: At 6 weeks, 3 months, 6 months, 1 year, 2 years

  3. Other RSA Measurements (Z-Translations)

    Other RSA measurements (Z translations in mm) at all time points

    Measured: At 6 weeks, 3 months, 6 months, 1 year, 2 years

  4. Other RSA Measurements (Rotations)

    X, Y, and Z rotations in degrees at all time points

    Measured: At 6 weeks, 3 months, 6 months, 1 year, 2 years

  5. Linear Head Penetration

    Linear head penetration at 1 year and 2 years for each surgical approach separately was reported.

    Measured: At 1 year and 2 years

  6. Patient Reported Outcome Measures (PROMs)- Harris Hip Score

    The Harris Hip Score (HHS) has 10 items with four subscales comprising a minimum of 0 points and a maximum of 100 points with higher scores representing better function and outcomes. The four subscales include: pain severity, activities of daily living, absence of deformity and range of motion. Scoring is done according to the following: 90-100 = excellent, 80-89 = good, 70-79 = fair, 60-69 = poor, and below 60 is a failed result.

    Measured: Pre Operation (-Day90 to Day 0), At 6 weeks, 3 months, 6 months, 1 year and 2 years

Questions about this trial

What is this clinical trial studying?

A study testing THA in people with Osteoarthritis and Degenerative Arthritis, run by DePuy Orthopaedics at 3 sites in Canada.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 19 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 21 Oct 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Mean Superior Cup Migration (Subsidence) at 6 Week and 2 Years (time frame: At 6 week and 2 years). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Dec 2025.
